When reading this documentation,​ [[https://​pics.me.me/​Instagram-Pictorial-representation-of-ohms-law-engineering-d05c8e.png|understanding]] of basic principles of electricity will be expected and can not be done without. ​

There is very little math in these videos ( except the last one ), if you have a hard time with what's still there, we warmly recommend heading over to [[https://​www.khanacademy.org/​|Khan Academy]]'​s math videos for easy to digest courses.
